Chemistry Basics
The amount of energy needed to start a chemical reaction.
What is activation energy?
A color change or production of light and heat are signs of this.
What is a chemical reaction.
When water hydrogen bonds with other substances that are not also water molecules.
What is adhesion?
The four types of macromolecules
What are carbohydrates, lipids, proteins, and nucleic acids?
An example of nucleic acids.
What is DNA or RNA?
All matter is made up of this.
What are atoms?
The bond that forms when electrons are given or taken away.
What are ionic bonds?
A water molecule has oppositely charged sides. Because of this property it can dissolve substances like salt (NaCl).
What is polarity?
The monomer of carbohydrates.
What is a monosaccharide?
An example of a carbohydrate?
What is glucose? (fructose, sucrose, lactose, etc)
A pure substance that cannot be broken down.
What is an element?
The type of bond that forms between the hydrogen and oxygen of one water molecule.
What is a covalent bond?
An example of a covalently bonded molecule.
What is water?
The monomer of lipids.
What are fatty acids and/or glycerol.
A type of protein that speeds up chemical reactions?
What is an enzyme?
An example of a heterogenous mixture.
What is oil and salt?
Water has a slightly negative charge at its oxygen and a slightly positive charge at its hydrogens because water is this type of molecule.
What is a polar molecule?
An example of an ionic compound that easily dissolves in water?
What is salt (NaCl)?
The monomer of proteins.
What are amino acids?
What you end with in a reaction.
What are products?
An example of a homogenous mixture.
What is salt water?
A type of reaction that releases energy.
What is an exergonic (or exothermic) reaction?
Hydrogen bonding or attraction between two water molecules.
What is cohesion?
The monomer of nucelic acids.
What are nucleotides?
What you start with in a reaction.
What are reactants?
